Contra-bevel driven control surface

An operator mechanism coupled between a control surface and an airfoil, comprising:

• a forward beveled member having an axis, an end coupled to the airfoil, another end having a bevel configuration, and selectively rotatable about its axis with respect to the airfoil;
• an aft beveled member having an axis, an end coupled to the control surface, another end having a beveled configuration, and the aft beveled member selectively rotatable about its axis with respect to the control surface;
• and
• a mid beveled member having an axis, an end with a bevel shaped configuration that mates with the end of the forward beveled member having the bevel and along a plane oriented oblique to the axes of the mid beveled and forward beveled members, and the mid beveled member having another end with a bevel shaped configuration that mates with the end of the aft beveled member having the bevel and along a plane oriented oblique to the axes of the mid beveled and aft beveled member, so that when at least one of the forward, aft, or mid beveled members is rotated, the control surface deflects with respect to the airfoil.

A method to reposition a control surface with respect to an airfoil, the method comprising:

• providing a control mechanism comprising:
• a first member having an axis, an end terminating along a plane oblique to the member axis and an opposite end coupled to the control surface and rotatable with respect to the control surface,
• a second member having an axis, an end that terminates along a plane oblique to the member axis and that is coupled to the beveled end of the first member, and an opposite end coupled to the airfoil and rotatable with respect to the airfoil;
• and
• changing the position of the first member with respect to the second member by rotating at least one of the first or second members about at least one of their respective axes to thereby deflect the control surface with respect to the airfoil.
